I sort of did this once, though it wasn't the typical kind of doctor and I didn't have much of a choice. I went to a trade school called Job Corps, and they are a pretty strict kind of school. Very military kinda thing, but not boot campish. Once you join, you are essentially stuck there through out the week. You can't typically leave campus on weekdays until you have earned the privileged too. You have to wake up super early, short time to shower, and you have to make your beds very neatly, military style. Couldn't even have stuffed animals. I tried and got in trouble XD.
Anyway, considering I am an AB/DL and I have a bit of a bed wetting problem, more often on purpose, but sometimes not. Eventually they just found out that I was a bed wetter. Kinda hard to hide something like that for very long. So .. they have doctors on center at all times and they sent me to them. Now of course, you can't blow them off, as you would get in serious trouble. Considering I had no where to go at the time and wanted to be successful ... getting in trouble was a no no.
So of course I didn't tell them I was an AB/DL and just told them that I was a bed wetter. Not entirely a lie, but partially. Now let me say, diapers was not what they recommended. Not even once. First it was medication. That really didn't work as it made me feel like crap ... and going out to drink, I found impossible to do unless you want to get wasted on 1 beer. I seriously blacked out off of 1 beer while taking those medication and normally I would only have a bit of a buzz with 2. Medication for urine reduction and alcohol is not a good combination. XD Those meds also made my mouth constantly feel dry.
So eventually I went back to them and told them, I didn't want to take meds. So the next thing they did was recommend catheters.
I have got to tell you, it was tough being a bed wetter with 3 other room mates and like 30+ dorm mates, 4 dorms in a building for over 100 in total. Even if they had eventually decides on diapers ... well ... no way to be discreet about that in such a situation. XD
I spent 3 years there. Close to my leave date, I was about to get thrown out due to the bed wetting. Lucky for me I convinced them .. that I had already been there this length . .what is a couple more months.
Edit: That experience essentially changed my entire perspective on being an AB/DL. I really began to no longer care who knew. I faced so much embarrassment it was hard to be embarrassed anymore.
